Terrible gas mileage, running rich?
#51
I just read the first few posts, so sorry if it's already been covered. You MUST MUST MUST tell us more, specifically whether your car is turbo or n/a, and it's good to know series 4 or 5 as well, and do it in the first post.
I would say it's likely that since your car is an n/a, you may not be actuating the fifth and sixth ports, which would cause you to run rich if you go above 3800 rpms. Then again, if you go above 3800 rpms, your gas milage will be bad anyways. Did you buy the exhaust used? is there any chance the catalytics are clogged?
Also, change your air filter.

sure you'll be slower in traffic but you'll also save gas. and you'll be a better driver

Here is a complete stab in the dark, for what it's worth.......
I have a 88 Chevy S-10 which would flood unless I removed the cover for the air filter and otherwise would run very rich. Ended up being the coolant temp sensor went bad, thus sending extra gas in to warm the engine up (because it always though it was cold). Possibly you are facing a similar situation?

One would hope, but no, I'm still getting 13/20 city/highway. I've more or less just accepted that for now; as far as passing smog is concerned, that probably isn't happening anymore though...
